Communication systems and methods of operating communication devices assigned individual and group unique identifiers

ABSTRACT

Described are systems and methods for operating a plurality of communication devices configured to be associated with a user group. Each communication device of the plurality of communication devices may be configured to communicate with one or more servers both as an individual communication device with an individual unique identifier assigned thereto and as the user group with a group unique identifier assigned thereto.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 13/840,046, filed Mar. 15, 2013 (U.S. Pat. No. 9,204,088), the disclosure of each of which is incorporated herein by this reference in its entirety.

TECHNICAL FIELD

Embodiments of the disclosure relate to operating a plurality of communication devices both as a user group and as individual communication devices within a communication system. More particularly, the disclosure relates to operation of video communication devices for the hearing impaired.

BACKGROUND

Video phone communication systems provide visual and audio communication between two or more users during a communication session. A video phone at a first location can transmit and receive audio and video signals to and from a video phone at a second location such that participants at the first location are perceived to be present or face-to-face with participants at a second location and vice versa.

Video phone communication systems span a variety of applications. One contemplated application of a video phone system includes facilitation of a communication session of a hearing-impaired user (e.g., deaf or hard of hearing), because many individuals with significant hearing loss are not able to communicate effectively over conventional telephone systems that rely upon voice communications. The hearing-impaired user may use a video phone during a communication session to relay his or her expressions over the video phone communication system. Such video phone communication systems may facilitate communication sessions between different hearing-impaired users (e.g., video phone to video phone communication), or between a hearing-impaired user and a hearing-capable user (e.g., video phone to voice phone communication), which may be assisted through a video relay service (VRS) that may provide an interpretive (i.e., translation) service by providing a hearing-capable translator who relays the expressions of the hearing-impaired caller to a hearing-capable user on the other end of the communication session in a conventional manner, such as through the use of a voice-based dialogue conveyed over a conventional voice phone. The hearing-capable translator may also translate the voice-based dialogue back to the hearing-impaired user into expressions (e.g., American Sign Language (ASL)).

As a consequence of the recent proliferation of communication devices, many people own several communication devices capable of video calls. For example, a single user may have one or more video phones at home, one or more video phones at their place of employment, a smart phone device, a tablet computer, a laptop computer, and/or a personal computer. The user may use some or all of these communication devices for video calls.

Conventionally, each of these communication devices is individually managed and is associated with separate user accounts. As a result, a user of multiple communication devices may be required to keep track of different log in credentials for each separate communication device. In addition, each individual communication device may have its own unique identifier (e.g., phone number, IP address, or other similar identifier used by a specific system) that is used to make and receive video calls. As a result, users have the burden of informing others what the unique identifiers are for each individual communication device so that others may contact them. Other people may also be inconvenienced by keeping track of several unique identifiers for the user when dialing a call to or receiving caller identification (caller ID) information from the user's various communication devices.

Also, having a plurality of different communication devices may become burdensome for the user to maintain information among each of their communication devices. For example, if a user desires to block an undesired caller, change device or account settings, access messages, or add new contacts to a directory on one of the communication devices, the action may need to be repeated separately on each of the rest of the communication devices. Furthermore, if a video call is missed on one of the communication devices, the user often only becomes aware of the missed call only when the user is again in the proximity of that particular communication device.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration, specific embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those of ordinary skill in the art to practice the disclosure. It should be understood, however, that the detailed description and the specific examples, while indicating examples of embodiments of the disclosure, are given by way of illustration only and not by way of limitation. From this disclosure, various substitutions, modifications, additions rearrangements, or combinations thereof within the scope of the disclosure may be made and will become apparent to those of ordinary skill in the art.

In accordance with common practice the various features illustrated in the drawings may not be drawn to scale. The illustrations presented herein are not meant to be actual views of any particular method, device, or system, but are merely idealized representations that are employed to describe various embodiments of the disclosure. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may be simplified for clarity. Thus, the drawings may not depict all of the components of a given apparatus (e.g., device) or all operations of a particular method.

Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof. Some drawings may illustrate signals as a single signal for clarity of presentation and description. It should be understood by a person of ordinary skill in the art that the signal may represent a bus of signals, wherein the bus may have a variety of bit widths and the disclosure may be implemented on any number of data signals including a single data signal.

The various illustrative logical blocks, modules, circuits, and algorithm acts described in connection with embodiments disclosed herein may be implemented as electronic hardware, computer software, or combinations of both. To clearly illustrate this interchangeability of hardware and software, various illustrative components, blocks, modules, circuits, and acts are described generally in terms of their functionality. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the embodiments of the disclosure described herein.

In addition, it is noted that the embodiments may be described in terms of a process that is depicted as a flowchart, a flow diagram, a structure diagram, or a block diagram. Although a flowchart may describe operational acts as a sequential process, process, many of these acts can be performed in another sequence, in parallel, or substantially concurrently. In addition, the order of the acts may be re-arranged. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc. Furthermore, the methods disclosed herein may be implemented in hardware, software, or both. If implemented in software, the functions may be stored or transmitted as one or more instructions (e.g., software code) on a computer-readable medium. Computer-readable media includes both computer storage media and communication media including any medium that facilitates transfer of a computer program from one place to another.

It should be understood that any reference to an element herein using a designation such as “first,” “second,” and so forth does not limit the quantity or order of those elements, unless such limitation is explicitly stated. Rather, these designations may be used herein as a convenient method of distinguishing between two or more elements or instances of an element. Thus, a reference to first and second elements does not mean that only two elements may be employed there or that the first element must precede the second element in some manner. Also, unless stated otherwise a set of elements may comprise one or more elements.

Elements described herein may include multiple instances of the same element. These elements may be generically indicated by a numerical designator (e.g., 110) and specifically indicated by the numerical indicator followed by an alphabetic designator (e.g., 110A) or a numeric indicator preceded by a “dash” (e.g., 110-1). For ease of following the description, for the most part, element number indicators begin with the number of the drawing on which the elements are introduced or most fully discussed. Thus, for example, element identifiers on a FIG. 1 will be mostly in the numerical format 1xx and elements on a FIG. 4 will be mostly in the numerical format 4xx.

Embodiments of the disclosure include systems and methods for operating a plurality of communication devices both as individual communication devices and as a member of a user group, which may include operating video communication devices in video communication systems. As discussed above, video communication systems span a variety of applications. Embodiments of the disclosure are generally described herein with reference to a video communication system for use by hearing-impaired users. Such video communication systems may facilitate communication sessions between different hearing-impaired users (e.g., video phone to video phone communication), or between a hearing-impaired user and a hearing-capable user (e.g., video phone to voice phone communication), which may be assisted through a video relay service (VRS). It should be noted, however, that embodiments of the disclosure may include any application or environment where operating a plurality of communication devices both as individual communication devices and as a member of a user group may be helpful or desirable. For example, it is contemplated that embodiments of the disclosure may include video communication session between hearing-capable users.

The term “call” refers to a communication with a communication device that may be routed through a number of networks, such as, for example, a private network, the internet, a telephone system, and a VRS. The term “incoming call” refers to an incoming communication to a communication device.

The term “communication device” may refer to a specific compilation of hardware components, software components, or a combination thereof. The term “communication device” may also refer to a software based communication device that exists on a device configured to execute machine-readable commands, such as, for example, a computer. As software, it should be understood that the same communication device may exist on a first device while a user accesses the communication device on the first device, and on a second device at a different time while the user accesses the communication device on the second device.

FIG. 1 is a simplified block diagram of a communication system 100, according to one embodiment. The communication system 100 may include a plurality of communication devices 202A₁, 202A₂, . . . 202A_(N), 202B₁, B₂, 202C (which are collectively referred to as communication devices 202). In some instances, reference may be made to an individual communication device by the generic designation of reference numeral 202. The communication system 100 may further include one or more servers 112, with which the communication devices 202 communicate through one or more networks 110. In other words, the communication devices 202 may be configured to establish communication with the one or more servers 112 (also referred to simply as “servers” 112) through the one or more networks 110 (also referred to simply as “networks” 110). The communication devices 202 may be configured to communicate with each other over a video call with the assistance of the servers 112, as described more fully below.

Each of the communication devices 202 may be assigned an individual unique identifier 130. In some instances, reference may be made to an individual unique identifier by the general designation of reference numeral 130. For example, communication devices 202A₁, 202A₂, . . . 202A_(N) may respectively be assigned an individual unique identifier 130A₁, 130A₂, . . . 130A_(N). In addition, the communication devices 202B₁, 202B₂ may respectively be assigned an individual unique identifier 130B₁, 130B₂. The communication device 202C may be assigned an individual unique identifier 130C. The individual unique identifier 130 is, therefore, device-centric rather than user-centric or location-centric. In other words, an individual unique identifier 130 may be associated with an individual communication device 202. In general, individual unique identifiers 130 are not shared by multiple communication devices 202. In some respects, an individual unique identifier 130 may be similar to a telephone number. For example, the individual unique identifier 130 may be used by other people to initiate video calls with the user of the communication device 202 associated with the individual unique identifier 130. In other respects, the individual unique identifier 130 may be similar to an IP address. For example, the individual unique identifier 130 may be used to identify the communication devices 202 to the servers 112. The individual unique identifier 130 may have a numerical format, such as an IP address or a phone number (e.g., a seven digit number, a ten digit number including an area code, etc.). The individual unique identifier 130 may have an alphabetic format (e.g., a word, a phrase, etc.), an alphanumerical format, or other suitable format used to uniquely identify an individual communication device 202. As another non-limiting example, the individual unique identifier 130 may be a Media Access Control (MAC) address, which uniquely identifies a network interface of the communication device 202.

The communication devices 202 may also be associated with one or more user groups 120A, 120B (which are collectively referred to as user groups 120). In some instances, reference may be made to an individual user group by the generic designation of reference numeral 120. A user group 120 may be an association (i.e., grouping) of communication devices 202 that are defined as members of the user group 120, as desired by a user. A user group 120 may be associated with any number of communication devices 202 so long as there are at least two communication devices 202 grouped together by the user. By way of non-limiting example, communication devices 202A₁, 202A₂, . . . 202A_(N) may be associated with a first user group 120A. The first user group 120A may be associated with a first user. Other communication devices 202B₁, 202B₂ may be associated with a second user group 120B. The second user group 120B may be associated with a second user. The communication system 100 may include communication devices 202, such as communication device 202C, which may not be associated with any user group.

The user groups 120A, 120B may respectively be assigned group unique identifiers 140A, 140B (which are collectively referred to as group unique identifiers 140). The group unique identifiers 140 are unique to a group rather than to an individual communication device 202. In other words, the group unique identifiers 140 are group-centric, such that the group unique identifiers 140 are not shared by other user groups 120. Therefore, individual communication devices 202 may be associated with both an individual unique identifier 130 and a group unique identifier 140. For example, a first communication device 202A₁ may be associated with the individual unique identifier 130A₁ and the group unique identifier 140A. Likewise, a second communication device 202A2 may be associated with the individual unique identifier 130A₂ and the group unique identifier 140A. Thus, because the first communication device 202A₁ and the second communication device 202A₂ are part of the same user group 120A, the first communication device 202A₁ and the second communication device 202A₂ share the same group unique identifier 140A (but not individual unique identifiers 130A₁, 130A₂). Other user groups (e.g., user group 120B) may be similarly configured.

A call may be initiated to the communication devices 202 by being addressed by either its individual unique identifier 130 or its group unique identifier 140. For example, if a person (e.g., the second user) calls the first user by entering the individual unique identifier 130A₁, only the individual communication device 202A₁ may indicate an incoming call. If, however, a person calls the first user by entering the group unique identifier 140A assigned to the first user group 120A, each of the communication devices 202A₁, 202A₂, . . . 202A_(N) of the first user group 120A may indicate an incoming call. An incoming call may be indicated visually, tactilely, audibly, or some other suitable indication, and combinations thereof. For hearing-impaired users, an incoming call may be indicated visually, tactilely, and combinations thereof.

As discussed above, the communication devices 202 may be associated with a user group 120 as desired by the user. In other words, the reasons for grouping the communication devices 202 within a particular user group 120 may be determined by the user acting as group organizer, rather than any particular limitation. For example, each communication device 202 belonging to a user group 120 need not be located in close proximity to each other. By way of non-limiting example, a single user group 120 may include a communication device 202 stationed at a user's dwelling, a communication device 202 at the user's place of employment, a communication device 202 at the user's cabin, and a portable communication device 202 that may be carried anywhere. It should also be understood that two or more communication devices 202 from the same user group 120 may be located proximate to each other. By way of non-limiting example, two or more communication devices 202 from the same user group 120 may be stationed in various locations of the user's home, such as in the living room, the kitchen, the bedroom, etc.

In addition, the communication devices 202 associated with a single user group 120 may belong to two or more users. By way of non-limiting example, communication devices 202 belonging to friends, family members, co-workers, and/or roommates may be part of a single user group 120. As a result, the user acting as the group organizer may invite others to join one or more of their communication devices 202 to join his group. For example, a user group 120 may be a group of co-workers within a team or practice group, such as a technical support team.

A single user group 120 may also include several different types of communication devices 202. By way of non-limiting example, an individual user group 120 may include any one or more of a personal computer, a smart phone, a tablet computer, and a video phone. In addition, a single user group 120 may include multiple communication devices from the same device type. For example, an individual user group 120 may have a plurality of video phones within the same individual user group 120. Furthermore, a single user group 120 may include any number of communication devices 202, limited only by the capacity of the communication system 100, and/or a desire to limit services to user groups 120 of a predetermined number of communication devices 202. By way of non-limiting example, administrators of a communication system 100 may choose to limit the number of communication devices 202 that a group organizer may be allowed to include within single user group 120 to a maximum number (e.g., five, six, etc.) of allowed communication devices 202.

The communication devices 202 may be configured to enable a user to participate in video calls with the other communication devices 202 of the communication system 100. A “video call” refers to communications where real-time or quasi real-time video data is exchanged between at least two parties. A video call may also refer to an attempted initiation of a real-time or quasi real-time video data exchange. For example, a first user using a first communication device 202A₁ may communicate with one or more other users using any of the other communication devices 202A₂, . . . 202A_(N) associated with the first user group 120A, the communication devices 202B₁, . . . 202B₂ associated with the second user group 120B, another communication device 202C not associated with a user group 120, and combinations thereof.

Any one of a variety of communication devices 202 may be configured to place and receive video calls, in part, because advancements in communication device technology have substantially increased the quantity, variety, and affordability of communication devices. By way of non-limiting example, the communication devices 202 may include any of a video phone, a desktop computer, a laptop computer, a tablet computer, a smart phone, and other suitable devices. Examples of a video phone include the NTOUCH® VP video phone and the VP-200 video phone available from SORENSON COMMUNICATIONS® of Salt Lake City, Utah. More device-level detail on the communication devices 202 is discussed below with reference to FIG. 2.

The networks 110 may include an internet protocol network configured to transmit communications between each of the plurality of communication devices 202 and the servers 112, such as by using an internet protocol (IP). The networks 110 may include a wide area network (WAN), a local area network (LAN), a personal area network (PAN), and combinations thereof. In some embodiments, the servers 112 may be part of a cloud network. The networks 110 may be configured to communicate with the plurality of communication devices 202 and the servers 112 wirelessly, through a cable, and combinations thereof. Some non-limiting examples of suitable wireless communications may include “Wi-Fi,” Bluetooth, and mobile wireless networks. Some non-limiting examples of suitable cables include fiber-optic cables, coaxial cables, traditional telephone cables, and Ethernet cables.

The servers 112 may be configured to provide services to the communication devices 202. For example, the servers 112 may be configured to manage calling functions, such as video call sessions and messages for the communication devices 202 of the communication system 100. In addition, the servers 112 may store and manage account information for the communication devices 202. Account information may include address books, account billings, and other information corresponding to the communication device 202 associated with the individual unique identifier 130. As non-limiting examples, the servers 112 may include a call routing server 114 and a profile server 116. Although discussed herein separately, the call routing server 114 and the profile server 116 may optionally be implemented as a single server device. Likewise, both the call routing server 114 and the profile server 116 may optionally include multiple server devices, and the various functions of the call routing server 114 and the profile server 116 may not necessarily be isolated to separate devices.

The call routing server 114 may be configured to set up and control a video call between one or more of the plurality of communication devices 202 and another of the plurality of communication devices 202, or a communication device associated with another user (not shown). The call routing server 114 may be configured to establish and control the video call through, for example, a session initiation protocol (SIP), or other suitable protocol.

The call routing server 114 may also periodically receive communications from each of the plurality of communication devices 202, including location or contact information, so that the call routing server 114 may locate and setup video call sessions with the communication devices 202 as needed. Also, the call routing server 114 may cause a particular communication device 202 to indicate an incoming call responsive to another person entering the individual unique identifier 130 assigned to the particular communication device 202. Furthermore, when the user enters the individual unique identifier 130 associated with another communication device 202 from one of the plurality of communication devices 202, the call routing server 114 may arrange for an outgoing call to be sent to the communication device 202 with the entered individual unique identifier 130 assigned thereto. In addition, when the user enters the group unique identifier 140 associated with a user group 120, the call routing server 114 may arrange for an outgoing call to be sent to each of the communication devices 202 associated with the entered group unique identifier 140 assigned thereto.

The profile server 116 may be configured to manage one or more user accounts associated with the individual unique identifiers 130. In some embodiments, the profile server 116 may also be configured to store information associated with each user account within the communication system 100. By way of non-limiting example, the profile server 116 may be configured to store an address book, a blocked caller list, a message history, text messages, video messages, a call history, personal user information, and combinations thereof, associated with each user account. In other embodiments, each of the communication devices 202 may be configured to store the information associated with the user account corresponding to the individual unique identifier 130 assigned thereto.

The servers 112 may be configured to enable the communication devices 202 to be associated with a user group 120. The user group 120 may, in some respects, function similarly to a separate communication device 102. For example, the user group 120 may be assigned a group unique identifier 140 and be associated with corresponding group account and group information, such as a group blocked caller list, a group message history, group text messages, group video messages, a group call history, a group address book (i.e., contact list), and combinations thereof, which may be stored on the profile server 116. Accessing any communication device 202 in the user group 120 may enable the user to access the group information, and communicate through the networks 110 using the group unique identifier 140 assigned to the user group 120. In some embodiments, group information may simply be a matter of the servers 112 being able to access individual communication device information that is stored for each communication device 202 to be shared with other communication devices 202 of the user group 120.

In some embodiments, where activity performed on a second communication device 202A₂ causes changes to the group information, the profile server 116 may communicate the changes in group information to the rest of the plurality of communication devices 202 belonging to the user group 120. Each of the plurality of communication devices 202 may be configured to periodically enter communication with the profile server 116 to receive updates. By way of non-limiting example, each of the plurality of communication devices 202 may be configured to enter communication with the profile server 116 approximately every five minutes (or other periodic interval) to receive updates. In some embodiments, updates may be event-driven such that certain events may cause the profile server 116 to broadcast updates to one or more of the communication devices 202. Initiation of these information updates and synchronizations may be performed by the servers 112 or the communication devices 202.

In some embodiments, the communication device 202 that is the creator of the user group 120 may have its information (e.g., lists) serve as the basis for the shared group information (e.g., shared lists). As discussed above, shared lists may include a blocked caller list, group message history, group text messages, group video messages, a group call history, a group address book (i.e., contact list). As a result, each of these group lists may be shared and accessible (for viewing, editing, adding to, etc.) by each communication device 202. If a shared group list is changed, the change may be saved within the profile server 116. In addition, the profile server 116 may broadcast a notification to each of the communication devices 202 within the user group 120 that a change has been made to the shared group lists and that their local cache needs to be updated. The individual communication devices 202 may respond (e.g., either immediately or at their next scheduled interval) to receive the updated information to store in their local cache. In addition, there may be shared settings (e.g., group settings) among group members that may be edited and shared in a similar manner. For example, shared settings may include the number of rings that occur before going to voice mail, a common voice mail message that is applied to all communication devices 202 rather than each communication device 202 having its own, among other similar settings.

In some embodiments, the profile server 116 and/or the individual communication devices 202 may retain a prior version of their individual lists and settings that existed before they joined the user group 120. As a result, when a communication device 202 leaves the user group 120, the communication device 202 may no longer have access to the shared group lists and settings and their lists may revert back to the individual state that the communication device maintained prior to joining the user group 120.

FIG. 2 is a simplified block diagram of a computing device. The computing device may be a communication device 202, according to certain embodiments. The computing device may also be a server 112, according to certain embodiments. The computing device, whether a server 112 or a communication device 202 will be referred to in the description of FIG. 2 as a communication device 202. The communication device 202 may be one of the communication devices 202 shown in FIG. 1. The communication device 202 may include a control device 204 operably coupled to a camera 206, a transceiver 210, and a user interface 222. The control device 204 may include at least a processor 226 and a memory device 228. The processor 226 may be configured to execute commands stored on the memory device 228. By way of non-limiting example, the memory device 228 may include a computer readable media, such as, read only memory (ROM), random access memory (RAM), flash memory, and combinations thereof. The control device may be configured to control the camera 206, and the user interface 222. In addition, the control device may be configured to cause the transceiver 210 to transmit and receive data through the networks 110.

The camera 206 may include devices capable of capturing and converting visual images to data, as will be readily apparent to those skilled in the art. By way of non-limiting example, the camera may include a webcam, a camcorder device, a camera device integrated into the same enclosure as the control device 204, and other suitable devices. The camera 206 may be operably coupled to the control device 204 and configured to deliver the data to the control device 204.

The user interface 222 may include an input device 224 and an output device 208 operably coupled to the control device 204. By way of non-limiting example, the input device 224 may include a keyboard, a numerical keypad, a mouse, a touch-screen, a button array, a track pad, a remote control, motion sensors, orientation sensors, position sensors, a microphone, and combinations thereof. The input device 224 may be configured to receive commands from the user. Also by way of non-limiting example, the output device 208 may include any of a light-emitting diode (LED) array, a segmented display, a liquid crystal display, a cathode ray tube display, a plasma display, and other electronic displays. The output device 208 may also include other peripheral output devices, such as speakers and vibrators. In some embodiments, the input device 224 and the output device 208 may be integrated in the same device, such as, for example, a touch-screen display. In other embodiments, the input device 224 and the output device 208 may be implemented in separate devices, such as a keyboard and an LCD monitor, respectively.

The control device 204 may cause the output device 208 to display video images received as data at the transceiver 210 during a video call. The control device 204 may also cause the output device 208 to display options on the output device 208, such as through a graphical user interface displayed on the output device 208. In addition, the control device 204 may execute user commands received by the input device 224.

The user interface 222 may enable the user of the communication device 202 to take several types of actions. Some of these actions may include logging in to the communication device 202 as a specific user, creating a new user group 120, inviting another communication device 202 to join a user group 120, withdrawing a communication device 202 from the user group 120, place a video call to another communication device 202, accept an incoming call from another communication device 202, access account information associated with the communication device 202, access account information associated with a user group 120 with which the communication device 202 is associated, etc.

FIGS. 3A and 3B illustrate a method for assigning a group unique identifier 140 to a user group 120, according to one embodiment. In particular, the first group 120A (FIG. 1) may receive a group unique identifier 140A to be associated with each of the communication devices 202 (FIG. 1) that are members of the first group 120A. As depicted in FIGS. 3A and 3B, the group unique identifier 140A may be a completely new identifier that was not previously an individual unique identifier 130A₁, 130A₂, 130A_(N) that is associated with one of the communication of the first user group 120A.

For example, the first user may decide to group together a plurality of communication devices 202, wherein each of the plurality of communication devices 202 have already been assigned their own individual unique identifiers 130. For example, the first communication device 202A₁ is associated with the first individual unique identifier 130A₁ of “0001,” the second communication device 202A₂ is associated with the second individual unique identifier 130A₂ of “0002,” and the Nth communication device 202A_(N) is associated with the Nth individual unique identifier 130A_(N) of “0003.”

As depicted in FIG. 3A, when the first user group 120A is created, the group unique identifier 140A may be unassigned. As depicted in FIG. 3B, the first user group 120A may be assigned a new group unique identifier 140A that was not previously assigned to any communication device 202 of the newly formed user group 120A. In other words, when the first user group 120A is created, the first user group 120A may be initialized with a new individual unique identifier 130A₁ assigned thereto. For example, the group unique identifier 140A assigned to the user group 120A is “0004.” The four digit unique identifiers 130, 140 are illustrated as a simple example of a unique identifier. As discussed above, the unique identifiers 130, 140 may be a telephone number, IP address, or other suitable identifier.

FIGS. 4A and 4B illustrate a method for assigning a group unique identifier 140 to a user group 120, according to another embodiment. In particular, the first group 120A (FIG. 1) may receive a group unique identifier 140A to be associated with each of the communication devices 202 (FIG. 1) that are members of the first group 120A. As depicted in FIGS. 4A and 4B, the group unique identifier 140A may be a selected from an existing individual unique identifier 130A that was previously an individual unique identifier 130A₁, 130A₂, 130A_(N) that is associated with one of the communication of the first user group 120A.

For example, in some embodiments, the group unique identifier 140A assigned to the user group 120A may be selected from among the individual unique identifiers 130A₁, 130A₂, . . . 130A_(N) that are part of the user group 120A. For example, the individual unique identifier 130A₁ of the first communication device 202A₁ may be “promoted” to be the group unique identifier 140A for the first user group 120A. As a result, the individual unique identifier 130A₁ (“0001”) previously associated with the first communication device 202A₁ may be “sacrificed” and becomes the unique identifier 140A for the first user group 120A. In some embodiments, another individual unique identifier 130A₁ (“0004”) may be assigned to the first communication device 202A₁ so that the first communication device 202A₁ may remain associated with both the individual unique identifier 130A₁ and the group unique identifier 140A associated with the first user group 120A.

When a user group 120 is established, the information (contacts, blocked calls, etc.) associated with the individual communication devices 202 may become group information (i.e., accessible through the other communication devices 202 of the user group 120), as desired by the user. In some embodiments involving a user group 120 initiated through promotion of an existing individual unique identifier 130 to become the group unique identifier 140 associated with the user group 120, only the information for that individual communication device 202 (e.g., communication device 202A₁) may be promoted to be group information.

Even though the establishment of the user group 120A is described with reference to FIGS. 3A, 3B, 4A, and 4B in terms of assigning the group unique identifier 140A to a newly established user group 120A, similar methods may be used to change the group unique identifier 140 after the user group 120 has been established. Therefore, the group unique identifier 140 assigned to the user group 120 may be changed by assigning a completely new group unique identifier 140 to the user group 120. In addition, the group unique identifier 140 may be changed by promoting one of the individual unique identifiers 130 to be the new group unique identifier 140 assigned to the user group 120, which may cause that a new individual unique identifier 130 be assigned to the corresponding communication device 202. In addition, the group unique identifier 140 associated with the user group 120 may be “demoted.” In other words, the group unique identifier 140 assigned to the user group 120 may once again become associated with a corresponding first communication device 202, and a new group unique identifier 140 may be assigned (e.g., new issuance, promotion, etc.) to the user group 120, or the user group 120 may be dissolved.

FIGS. 5A and 5B are data flow charts 530, 548 illustrating data flow between a communication device 202, a profile server 116, and a database 560 associated with the profile server 116. FIG. 5A illustrates data flow resulting from communication device 202 logging in with individual credentials associated with the communication device to access account information. FIG. 5B illustrates data flow resulting from the communication device 202 logging in with group credentials associated with a user group 120 to access account information, the communication device 202 belonging to the user group 120.

The database 560 may be configured to store individual account information corresponding to the communication device 202 and group account information corresponding to a user group 120 (FIG. 1) to which the communication device 202 belongs. Individual account information may include valid individual log in credentials (also referred to herein as “individual credentials”), user information, and individual communication device 202 information associated with the communication device 202. Group account information may include valid group log in credentials (also referred to herein as “group credentials”), user information, and group information associated with the user group. The group account information may also include information corresponding to a plurality of communication devices 202 that belong to the user group 120.

Referring to FIG. 5A, the user of the communication device 202 may provide individual credentials through the user interface 222 (FIG. 2) of the communication device 202. By way of non-limiting example, the individual credentials may be a user name and password. In some embodiments, the user name may be the individual unique identifier 130 assigned to the communication device 202. Other individual credentials, such as, for example, a user selected user name, are also contemplated.

At operation 532, the communication device 202 may send the individual credentials through the networks 110 (FIG. 1) to the profile server 116. At operation 534, the profile server 116 may send a validation request to the database 560 to validate the individual credentials provided by the user against the valid individual credentials stored in the database 560.

At operation 536, the database 560 may send a success/failure signal to the profile server 116 indicating either success or failure of the log in attempted by the user of the communication device 202. If the individual credentials provided by the user of the communication device 202 do not match those stored in the database 560, then the success/failure signal sent to the profile server 116 may indicate failure of the log in attempt. As a result, the user may not be given access to account information. If, on the other hand, the log in credentials provided by the user of the communication device 202 match those stored on the database 560, the success/failure signal sent to the profile server 116 may indicate a successful log in attempt. As a result, the user may be given access to the individual account information.

In some embodiments, the profile server 116 may also cause the communication device to give the user access to the group account information along with the individual account information if the communication device 202 belongs to the user group 120. If, however, the communication device 202 is not associated with the user group 120, then the profile server 116 may cause the communication device 202 to only access the individual account information. In other embodiments, logging in with the individual credentials may exclude the communication device 202 from accessing the group account information regardless of whether the communication device 202 belongs to the user group.

If the log in attempt succeeds, at operation 538 the profile server 116 may query the database 560 to determine whether the communication device 202 belongs to a user group 120. At operation 540, the database 560 may send the group account information to the profile server 116 if the communication device 202 is part of the user group 120. If, on the other hand, the communication device 202 is not part of the user group 120, the database 560 may only send the individual account information, and not the group account information.

The profile server 116 may create a session and cause a session identifier to be stored on the database 560 at operation 542. At operation 544, the database may send the session identifier to the profile server 116. At operation 546, the profile server 116 may send the session identifier through the networks 110 to the communication device 202, and the user may operate the communication device 202 as both the communication device 202 and the user group 120 if the communication device 202 belongs to the user group 120, and only as the communication device 202 if the communication device 202 does not belong to the user group 120.

Referring to FIG. 5B, the user of the communication device 202 may provide group credentials through the user interface 222 (FIG. 2) of the communication device 202. The group credentials may include a user name and password. In some embodiments, the user name may be the group unique identifier 140 assigned to the communication device 202. Other group credentials, such as, for example, a user selected username, are also contemplated.

At operation 550, the communication device 202 may send the group credentials through the networks 110 (FIG. 1) to the profile server 116. At operation 552, the profile server 116 may send a validation request to the database 560 to validate the group credentials provided by the user against the valid group credentials stored in the database 560.

At operation 554, the database 560 may send a success/failure signal to the profile server 116 indicating either success or failure of the log in attempted by the user of the communication device 202. If the group credentials provided by the user of the communication device 202 do not match those stored in the database 560, then the success/failure signal sent to the profile server 116 may indicate failure of the log in attempt. As a result, the user may not be given access to account information. If, on the other hand, the group credentials provided by the user of the communication device 202 match those stored on the database 560, the success/failure signal sent to the profile server 116 may indicate a successful log in attempt. As a result, the user may be given access to the group account information.

If the log in attempt succeeds, at operation 556 the profile server 116 may query the database 560 to determine whether the communication device 202 belongs to a user group 120. At operation 558, the database 560 may send the group account information to the profile server 116 if the communication device 202 is part of the user group 120. If, on the other hand, the communication device 202 is not part of the user group 120, the database 560 may not send the group account information.

Once the user succeeds in logging in with group credentials, at operation 596 the profile server 116 may attempt to determine which individual account information to give the communication device 202 access to along with the group account information. If the profile server 116 succeeds in determining which individual account information to provide, the profile server 116 may create a session and cause a session identifier to be stored on the database 560 at operation 598. At operation 501, the database may send the session identifier to the profile server 116. At operation 503, the profile server 116 may send the session identifier through the networks 110 to the communication device 202, and the user may operate the communication device 202 as both the communication device 202 and the user group 120.

Returning to operation 596, if the profile server cannot determine which individual account information to provide to the user, at operation 505 the profile server may send the group account information to the communication device 202 and query the user to indicate which individual account information to provide. At operation 507, the user may indicate the individual account information that should be provided, and the indication may be sent to the profile server 116. At operation 509, the profile server may create a session, and cause a session identifier to be stored in the database 560. The database 560 may send the session identifier to the profile server 116 at operation 511, and the profile server 116 may send the session identifier through the networks 110 to the communication device 202 at operation 513. The user may then operate the communication device 202 as both the communication device 202 and the user group 120. As a result, using a group unique identifier 140 to log in may also cause the communication device 202 to communicate with the one or more servers 112 responsive to being addressed by the individual unique identifier 130 assigned to the communication device.

FIG. 6 is a flowchart 662 of a method for adding a communication device 202 (FIGS. 1 and 2) to a new or existing user group 120. At operation 664, the user interface 222 (FIG. 2) may display a welcome screen to a user of the communication device 202. At operation 668, the user interface 222 may display an option to join a user group 120 (FIG. 1). If the user rejects the option to join a user group 120, at operation 672 the user interface 222 may display a cancel screen, and at operation 688 the method may end. If the user accepts the option to join a user group 120, at operation 670 the user interface 222 may provide an option to create a new user group 120.

If the option to create a new user group 120 is accepted, at operation 676 the user interface 222 may display an agreement delineating any terms required for creating the new user group 120, and an opportunity is provided to accept or reject the agreement. If the agreement is rejected, at operation 672 the user interface 222 may display the cancel screen, and at operation 688 the method may end. If, on the other hand, the agreement is accepted, at operation 680 the user interface 222 may prompt the user to set group credentials, including, for example, a group unique identifier 140 (FIG. 1) and a password. At operation 684 the user interface 222 may prompt the user to add other communication devices 202 to the new user group 120. The profile server 116 (FIG. 2) may send invitations to join the new user group 120 to any communication devices 202 added by the user. At operation 686, the user interface 222 may provide the user an option to activate the new user group 120. If the user elects to activate the new user group 120, the new user group 120 may be activated, and at operation 688 the method may end. If the user elects not to activate the new user group 120, at operation 672 the cancel screen may be displayed, and at operation 688, the method may end.

Going back to operation 670, if the option to create a new user group 120 is denied, the user interface 222 may prompt the user to enter existing user group 120 credentials at operation 674. At operation 678, if the credentials are not correct, the user interface 222 may once again prompt the user to enter existing user group 120 credentials at operation 674. At operation 678, if the credentials are correct, the communication device 202 may be added to the existing user group 120 at operation 682. At operation 688 the method may end.

FIGS. 7A through 7F are simplified block diagrams of a communication system 700 illustrating some examples of some of a plurality of communication devices 702A₁, 702A₂, . . . 702A_(N), 702B₁, 702B₂, 702C, 702D (referred to herein collectively as communication devices 702) operating both as individuals and as user groups 720A, 720B (referred to herein collectively as user groups 720) within a communication system 700. FIG. 7A is a simplified block diagram of the communication system 700, including the communication devices 702, and one or more servers 712 (referred to herein as the servers 712). The communication system of FIGS. 7A through 7F is similar to the communication system 100 of FIG. 1, except FIGS. 7A through 7F do not show the network 110, and FIGS. 7A through 7F include an additional communication device 702D not shown in FIG. 1. Although the networks 110 of FIG. 1 are not shown in FIGS. 7A through 7F, it should be understood that interactions between the communication devices 702, and between the communication devices 702 and the servers 712 occur through one or more networks similar to the networks 110 of FIG. 1.

In FIGS. 7B through 7F, not all the reference numerals shown in FIG. 7A are shown. Those reference numerals referred to specifically with respect to each of FIGS. 7B through 7F are shown, along with the communication system 700 reference numeral, user group reference numerals 720, and communication device reference numerals 702.

The communication devices 702 and the servers 712 may be similar to the communication devices 202 and the servers 112 of FIG. 1. Some of the plurality of communication devices 702 may be associated with a user group 720. By way non-limiting example, communication devices 702A₁, 702A₂, . . . 702A_(N) may be associated with a first user group 720A, and communication devices 702B₁, 702B₂ may be associated with a second user group 720B. Other communication devices 702 may not be associated with any user group 720. For example, communication devices 702C, 702D may not be associated with any user group.

Each of the communication devices 702 may be assigned an individual unique identifier 730. By way of non-limiting example, communication devices 702A₁, 702A₂, . . . 702A_(N), 702B₁, 702B₂, 702C, 702D may be assigned individual unique identifiers 730A₁, 730A₂, . . . 730A_(N), 730B₁, 730B₂, 730C, 730D, respectively. The individual unique identifiers 730 are similar to the individual unique identifiers of FIG. 1. In FIGS. 7A through 7F, each of the individual unique identifiers 730 are four-digit numbers. The disclosure, however, is not so limiting. As discussed above with respect to the individual unique identifiers 130 of FIG. 1, the individual unique identifiers 730 may take various forms.

Each of the user groups 720 may be assigned a group unique identifier 740. By way of non-limiting example, the first user group 720A may be assigned a first group unique identifier 740A, and the second user group 720B may be assigned a second group unique identifier 740B. The group unique identifiers 740 are similar to the group unique identifiers of FIG. 1. In FIGS. 7A through 7F, each of the group unique identifiers 740 are four-digit numbers. The disclosure, however, is not so limiting. Similar to the individual unique identifiers 730, group unique identifiers 740 may take various forms.

The communication devices associated with a user group may be configured to operate in the communication system 700 both as individual communication devices 702 assigned individual unique identifiers 730, and as members of the user group 720. Those communication devices 702 not associated with a user group 720 may operate as individual communication devices 702 assigned individual unique identifiers 730.

Each of the communication devices 702 may be configured to send a call request 794 (FIGS. 7B through 7F) through the servers 712. The call request 794 may indicate an individual unique identifier 730 assigned to a communication device 702, or a group unique identifier 740 assigned to a user group 720, that a user initiating the call request 794 desires to call.

Each of the communication devices may include an incoming call indicator 790, and a caller identification indicator 792 (incoming call indicators 790A₁, 790A₂, . . . 790A_(N), 790B₁, 790B₂, 790C, 790D are included in communication devices 702A₁, 702A₂, . . . 702A_(N), 702B₁, 702B₂, 702C, 702D, respectively, and caller identification indicators 792A₁, 792A₂, . . . 792A_(N), 792B₁, 792B₂, 792C, 792D are included in communication devices 702A₁, 702A₂, . . . 702A_(N), 702B₁, 702B₂, 702C, 702D, respectively). The incoming call indicator 790 may be configured to indicate an incoming call. By way of non-limiting example, the incoming call indicator 790 may indicate the incoming call visually, tactilely, audibly, some other suitable indication, and combinations thereof.

Responsive to receiving a call request 794 indicating an individual unique identifier 730, the servers 712 may cause only the communication device 702 with the individual unique identifier 730 indicated in the call request 794 assigned thereto to indicate an incoming call with its incoming call indicator 790. Also, responsive to receiving a call request 794 indicating a group unique identifier 740, the servers 712 may cause all the communication devices 702 associated with a user group 720 with the group unique identifier 740 indicated in the call request 794 assigned thereto to indicate an incoming call.

The caller identification indicator 792 may be configured to indicate a source of an incoming call. The caller identification indicator 792 may be configured to indicate a user group 720 if the communication device 702 initiating the call request 794 is associated with the user group 720 and logged in with the group unique identifier 740. The caller identification indicator 792 may be configured to indicate the individual communication device 702 initiating the call request 794 if it is not associated with a user group 720.

In some instances, a first communication device 702 associated with a user group 720 may be logged in to a first communication device with an individual unique identifier 730 assigned to the first communication device 702, instead of with the group unique identifier 740. In some embodiments, a second communication device 702 that receives the call from the first communication device may still indicate the group unique identification 740 of the user group 720 that the first communication device 702 is associated with on its caller identification indicator 792. In other embodiments, the second communication device 702 may indicate the individual unique identification 730 assigned to the first communication device 702.

Each of the caller identification indicators 792 of FIGS. 7A through 7F include a field of a display configured to display an individual unique identifier 730 or a group unique identifier assigned to a communication device 702 or user group 720 that is the source of the call request 794 triggering the incoming call. In other embodiments, the caller identification indicator 792 may be configured to display a photograph of one or more user of the communication device 702 or user group 720 that placed the call request 794. In additional embodiments, the caller identification indicator 792 may be configured to display a graphic, a text string, a nickname, or a name of a user of the communication device 702 or user group 720 that placed the call request 794. In still other embodiments, the caller identification indicator 792 may indicate a source of an incoming call with visual, tactile, and/or audible patterns. By way of non-limiting example, U.S. Pat. No. 7,769,141 to Cupal et al., the disclosure of which is incorporated herein by reference in its entirety, discloses a caller identification visual alerting device including a spatial visual indicator configured to activate a plurality of illuminable elements in a pattern corresponding to a source of an incoming call. Also by way of non-limiting example, U.S. Patent Publication 2012/0196580 to Simmons et al., the disclosure of which is incorporated herein by reference in its entirety, discloses a caller identification device configured to generate tactile patterns associated with a source of an incoming call.

FIG. 7B illustrates an example of a call request 794 initiated by a communication device 702C not associated with a user group 720, and directed to a communication device 702D also not associated with a user group 720. The servers 712 may receive the call request 794 from communication device 702C indicating individual unique identifier 730D (0987) assigned to communication device 702D. In response to the call request 794, the servers 712 may cause communication device 702D to indicate an incoming call with the incoming call indicator 790D (darkened and accentuated with lines to show incoming call indicator 790D indicating an incoming call). The servers 712 may also cause the caller identification indicator 792D to indicate the individual unique identifier 730C (8765) of the communication device 702C initiating the call.

FIG. 7C illustrates an example of a call request 794 initiated by a communication device 702C not associated with a user group 720, and directed to a communication device 702A₁ that is associated with a user group 720A. The servers 712 may receive the call request 794 from communication device 702C indicating individual unique identifier 730A₁ (1234) assigned to communication device 702A₁. In response to the call request 794, the servers 712 may cause communication device 702A₁ to indicate an incoming call with the incoming call indicator 790A₁ (darkened and accentuated with lines to show incoming call indicator 790D indicating an incoming call). The servers 712 may also cause the caller identification indicator 792A₁ to indicate the individual unique identifier 730C (8765) of the communication device 702C initiating the call.

As the call request 794 indicated the individual unique identifier 730A₁ (1234), the servers 712 did not cause the other communication devices 702A₂, . . . 702A_(N) to indicate the incoming call or the source of the incoming call. Each communication device 702 associated with a user group 720 thus retains its identity as an individual communication device 702 despite its association with a user group 720. Any communication device 702 may send a call request 794 that may cause only one communication device 702 of a user group 720 to indicate an incoming call.

FIG. 7D illustrates an example of a call request 794 initiated by a communication device 702C not associated with a user group 720, and directed to a user group 720A.
